## Which one, for what

### Capsule CRM (C)

Good for: Small teams already on Capsule who want an agent to read and write contacts, opportunities, projects and tasks over REST with a read-only scope available.

Ahead on:
- Reliability, 83 against 61
- Payments & pricing, 30 against 10
- Maintenance & community, 38 against 22

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No OpenAPI file, llms.txt or official SDK was found

### SugarAI (SugarCRM) (D)

Good for: Companies already running Sugar Sell, Serve or Enterprise that want an agent to read and write records under a named user's roles, and that have Sugar's approval for the integration.

Ahead on:
- Agent ergonomics, 69 against 59
- Security & auth, 51 against 46

Watch for: The AI Supplemental Terms forbid connecting customer-owned or third-party AI systems, agents or MCP connectors to the Services or APIs except through functionality Sugar has approved. This matters before any probe is run

## Verdicts

**Capsule CRM.** REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

**SugarAI (SugarCRM).** The REST reference covers 350 endpoint pages with filters, field selection, bulk calls and upsert by `sync_key`. SugarAI's AI Supplemental Terms forbid connecting a customer's or third party's AI agent or MCP connector to the APIs unless Sugar has approved it, tokens carry no scopes, and no OpenAPI file, trial or SLA was found.

## Before you call either

### Capsule CRM

1. Send `Authorization: Bearer <token>` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`
2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50
3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls
4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`
5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

### SugarAI (SugarCRM)

1. Confirm that Sugar has approved the agent integration before connecting. The AI Supplemental Terms forbid unapproved AI agents and MCP connectors on the APIs
2. POST to `/rest/v11_27/oauth2/token` with `grant_type` `password` and a `platform` other than `base`, `mobile` or `portal`, or the login can end the user's own session
3. Send the access token in the `OAuth-Token` header. It lasts 60 minutes by default, so store the refresh token and not the password
4. Stay under 20 requests a second on SugarCloud and reuse one session for batches. Over-limit traffic is blocked by IP address until support lifts it
5. Page with `max_num` and `offset` until `next_offset` is -1, and pass `fields` to keep responses small
6. Use `PATCH /integrate/:module/:sync_key_field_name/:sync_key_field_value` for writes that may be retried, since it inserts or updates by `sync_key`
